Issue with Unbrick guide(method) - LG Nitro HD

Hi there guys searched around and relaly dont see a similiar problem I am having and any help would be appreciated. So I flashed the ics leak forthe unrooted v ersion of my att&t nitro that worked fine(its the exact same one as hono's but for unrooted roms) Anyways now that att official is coming out I wish to downgrade back to a stock rom so it will update to official. problem is during the unbrick method as its at some points in broken english(not a dis) just saying can get a bit confusing.
So I get to the step where the lg tool is updating and reboots phone and phone is back on and we are at about 93 percent that the problem occurs. the program(lg tool) says that there is a problem with the usb connection to the phone communicating please pull out usb remove battery and turn phone back on and hit restart ive tried that and still gets to same point to eventually program gives up and say exit.
ive reinstalled teh shttp server and all the tools redownloaded the linked kdz file etc...cant i just flash the official att rom since im not actually bricked. or is it better to dowgrade and redo it how i am trying to do now. Any hlep is appreciated seems as newer phones come out things get more confusing then easier

i recommend you to use the original data cable that came alongwith the phone package and the usb ports at the back of the pc !
do this and try again !

yeah I am using the data cable that came with it and using the usb ports on back of pc. also i assume I cannot access the adb commands via the command line if phone isnt rooted correct? because i have t ried but thats a no go but as i said i assume thats because im not rooted.

You shouldn't have any reason to downgrade. You should just be able to use the LG tool to install the new ICS version when it "officially" comes out without any fuss.
If you want to install it right away (but slightly more difficult method), then follow the unbricking guide but use the new AT&T KDZ file instead of the one listed in the guide. And stop after it flashes that because you're done.

ok i assume the new att kdz is on this forum so i will look for it and give it a go i know the link hono had up yesterday for official attv20 was dead link.

oh another question when ya luanch the R&D test tool(UpTestEX_mod2_marwin.exe ) for select type do i leave it at cdma? and for phone mode leave it in diag? or should it be in emergency or cs_emergency that is not listed in the guide

ok got it to work i had to block the 127.0.0.1 lgmobile line in host and rebooted computer and pointed model dll on the R&D tool to the one in kd folder and then used the v20 official att ics and slet it stay on korean as country but chose english as language,thanks for hte help.

Root Telus P935?

Has anyone with a telus optimus lte (p935) been able to root?
I've tried super one click and the manual method but both get hung up at the same place (step 7). Tried over 20 times, dubugging is on, screen timeout set to 10 mins, freshly booted, etc. Even tried z4root with no luck.
Help?
Sent from my LG-P935 using XDA App
The P935 uses a firmware version that cannot be rooted. v10k is not root-able, but v10f and I believe v10i are root-able.

Is there a method to down/upgrade to a rootable version?
Thanks for the response btw.
I don't have a P935, so I can't say what the process would be for the downgrade. If I pointed you in the process for the Nitro HD/Optimus LTE P930, you could end up with a brick.

I myself have had no luck. After reading that it's possible the p930 & p935 are in some way different (Somehow I doubt it, they're the exact same device including radio) I stopped trying as there will never be a p935 specific forum. I'm content to wait until ICS arrives. I'm no rom cook, so root without many/any roms is reasonably useless to me.
no root for me either.
tried a lot of the tools out there (and all the versions of them too),
they just seem to try and write to the phones memory and fail. Then reboot the phone, and nothing changes.
Good thing I saw this! I'm in the market for a Canadian Optimus LTE/Nitro HD. Didn't know the Bell and Telus ones are different!
[Once CM9 is released for the P930, I assume it won't "just work" on the P935?]
It won't just work for the p935....as there is something different with the phone.

The firmware version on the P935 is v10a. I've yet to find information on the possibility of rooting this. Just about giving up on this & ready to sell it.

I believe I have tried every product out there. Never had such a hard time rooting. I am doing a final search today and then giving up.
Disgusted at the idea of not being a poweruser. Might as well just have bought an iphone. Disgusted.
Anyone want a great unrootable phone?

Unrooted is useless to me and won't allow me to remove Facebook. Anyway, any suggestions on a comparable phone to buy? This one rocks except it's unrootable. Love the LTE & speed but battery life is a joke. Less than 2 hours while doing nothing and the processor overheats when doing something.
Making an unrootable phone of this caliber is a joke.
Just an update:
I took a risk and attempted to to load the v10k & v10i per the unbrick/downgrade instructions and ended up soft bricking my phone. I tried again and again to re-flash but it kept hanging at the LG Optimus LTE boot screen. I left the phone for a week, then saw the OTHER way of flashing, using small http server, etc.
Tried THAT method and voila, it booted the su640 rom! I've rooted, installed CWM & in the process of installing the CM9 daily.
Things i noticed right away is that screen rotation was off by 90 degrees & wifi didn't work in the korean rom. Voice & Data worked fine after adding my the APN.
For the record, this is a Telus p935. I do NOT recommend trying this as it was messy & more than likely would have ended up with a permenant brick without a Telus KDZ.
Edit: CM9 installed just fine. Rotation works perfect & wifi works as well. Voice, data... it's all there.

Can you please write a somewhat noob friendly write up for people who are stuck on unrootable phones?
Thank you!!
How to: Root Telus p935
Standard disclaimer: I am not responsible for anything that happens to your phone. It worked for me, may not work for you.
So here is how I rooted my Telus p935:
My original firmware was v10a dated sometime in Jan 2012.
Initially I tried to flash using this guide:
http://forum.xda-developers.com/showthread.php?t=1412367 <---- do not use this guide
What ended up happening is my phone would boot and get stuck at the Optimus LTE splash screen. I tried v10i, v10f over and over and nothing would get it past that same splash screen. I had let the phone sit for about a week until I came across this method for flashing:
http://forum.xda-developers.com/showthread.php?t=1554255 <---- Use this one
Seeing that my phone was already soft bricked, I really had nothing to lose. So I followed the guide step by step and it ended up booting (!!!) the korean v10f rom.
This is how it looked while it was updating:
1) The percent bar in the upgrade software did not move past 4% the entire time
2) Inside the "activity window" there was an incremental error message that ticked up until it got to about 94 and the phone would reboot. Looked like this:
2:06:40 : MODEL DLL Event : (2004, 42)
12:06:40 : Model Dll Msg Not Found(2004, 42)
12:06:44 : wParam : 2004, lParam = 43
12:06:44 : MODEL DLL Event : (2004, 43)
12:06:44 : Model Dll Msg Not Found(2004, 43)
After I flashed it the first time, I appeared to be stuck at the same place, so while I was on the "Optimus LTE" splash screen, I started to flash AGAIN. I walked away as it was updating the second time, but I assume it went through the same process as it did the first time, but I heard the boot animation of the v10f rom..... and it completed the boot.
Once I was in the v10f rom, I followed the manual root guide here:
http://forum.xda-developers.com/showthread.php?t=1407076
Rotation was off 90 degrees in the rom and wifi didn't work. If you need mobile data, use these APN settings:
http://forum.xda-developers.com/showthread.php?t=1434995
This allowed me to flash CWM recovery and begin flashing roms per usual. Note that ROM Manager flashed the TOUCH version of CWM which didn't read the SD Card properly! I had to manually flash the non-touch version located here:
http://forum.xda-developers.com/showthread.php?t=1410454
So that's it, I'm now running the AOKP port & enjoying being away from LG firmware. If this works for you, post here so we can confirm it's working on more than just my phone
Some tips:
- Find v10f kdz, I didn't bother linking it here
- You must follow the guides to the LETTER
- Do not use the touch cwm
- If the manual root guide gives you root but doesn't install superuser, just download it from the market (Wifi won't work in v10f, use mobile data)
- Be patient
Hopefully this is noob-proof enough! Good luck!
Bytecode64's version of CWM had some major issues and should not be used anymore. You should be using the Touch CWM on these devices.
The SD card issue can be fixed. The problem is with the way the SD cards that are included with the phone are formatted from the factory. To fix it, use this application to format your SD card from a computer: https://www.sdcard.org/downloads/formatter_3/ . (Don't just re-format using Windows, it won't work.) If you want to preserve the files on your SD card, you can simply make a copy of them before formatting then re-copy them back onto the card. After that it should work fine in Touch CWM.
So, good to hear!!!
Is there a KDZ for the V10a?
is there a way for me to back it up? Just in case?
But can't wait to try it!!!
cheers!!!
It worked!
Um Yeah Didnt Work For me, I did everything to a t and now stuck at the LG Optimus LTE update screen, tried doing a hard reset, and Battery removal but my phone is kinda stuck in limbo
and when I try to update a second time its says it has trouble communicating with the Phone..............
EDIT!
I got it to Work After I switched the Uptest Program to CDMA, just testing seeing how everything works! ANd thankyou for Posting the tutorial Dashaiva!
I also rooted the su640 rom with a program called UnlockRoot, then proceeded to install touch CWM, and am now running CM9, and same as Dashaiva the su640 rom was off 90 degrees and no Wifi

Is the phone in download mode? Did you press vol up + insert micro usb? And you're using the guide that involves small http server?

Never seen a copy of v10a, if you do this there is no going back so far.
I also had the v10a, but after I used the CDMA setting, and CSE upgrade, it went to about 90 percent but then failed. It stayed in download mode,turned it off.then hard reset using power and volume down, it showed the Lg Optimus Screen and Booted into the Korean rom
Sent from my LG-P930 using XDA
I used superoneclick 2.3.3 to root my optimus with android 2.3.5 on
V11a and it worked using zergrush method, and im with Bell.

Can't go back to stock

OK, so I have a big problem.
My screen suddendly stopped reponding on a large middle portion of it, so I'm sending it off for repair or exchange. I was rooted and running a custom rom (infected CM11), so I wanted to get it back to stock before.
But I followed every damn tutorial I could find in here, as well as in LG G2 and Optimus' forums, but it just won't work. R&D test tool keeps opening LG flash tool, and just refuses to flash the KDZ I have sideloaded.
The big issue might be this : I have lost my serial number when I flashed the KK leak, and I have sent my original sticker to LG because where I live, there was a 50€ off offer that required me to send it to them. I found on the internet a serial number, and it seems to be working.
Anyone has an idea as to what I might do ?

I also lost my serial with the leaked 4.4.2, however I just flashed my backup and got it back. If you have a backup (which you really always should do), flash it and then follow the tutorial to return to stock again. If you dont have a backup I dont really know but you could try flash CM again.

I had a backup, but not from Stock Rom, and my serial with AOSP seems to be different... I'm in the process of flashing with an offline procedure, but it's hanging at 4%.

[Q] TWRP bricked My LG optimus G Pro...help

I can't access files from usb or micro sd. Can't connect to my lap top. How am I supposed to put a ROM on my LG? The TWRP is loaded, but I have no rom on the internal SD, so there is nothing to recover. TWRP is like a virus, it wiped out my phone. I can access the terminal mode on the phone, but how do I use that to load a rom? All I can find is Greek to me, stand on one leg, look west, hack a key, toss some salt over your shoulder, blah, blah, blah. There must be a simpler solution. This isn't a recovery project, its a destruction project. I used a custom recovery a few years back with no trouble on my Samsung I897. Please, if u understand how TWRP works, help me out.
Vic
As far as I know, Twrp for optimus g pro can't read the external SD card. Have you download the lg device drivers and install them on your laptop? Sounds like you haven't done so, otherwise your computer should be able to read your device. Once you establish the connection, you be able to transfer the file or flash the oem firmware. Everything you need is on this forum, search the topic on flashing the stock rom, there you will find the device drivers. Understand your frustration, but half of your posting is you *****in' and that doesn't help.

Before TWRP killed my phone, I was rooted and was able to connect my laptop to my phone no problem. I tried reloading LG drivers, but when I plug the phone in to USB, the Laptop tells me there is something wrong with the device, doesn't recognize it.

Have you try adb side load? If you have 2.3 or higher version of Twrp, you should have the side load function. Within adb you can push the file into which ever directory in your device. Other than the side load, you may have to flash the either cwm image file with lg flash tool or flash the stock rom and go from there.
ADB Sideload, yes I have it

Although I have the ADB Sideload, I'm not sure how to use it. I can access it on the phone, but isn't the idea to use it from your laptop to move files over to the internal SD. How do I get an ADB on my laptop that will talk to the adb sideload of the phone? I tried using the ADB console of my super one click, but it could not see my phone. Sorry to be such a nub about this, but every problem is a new one to me.

You have to flash the base-band if you don't get signal KDZ''ing other phones KDZ, try the e980 Central America or the Mexico Telcel 980 one preferable the telcel since that's what he states will work. Also if a site isn't in English use Google translate or use Google Chrome browser it will translate web pages for you.

Everything you need is on this forum, search the topic on flashing the stock rom, there you will find the device drivers. Understand your frustration, but half of your posting is you *****in' and that doesn't help.

I now have bigger problems. I can only flash roms that are Korean in Language. Even though I pick English, when the flash is done I get Korean. I have tried numerous of the kdz roms, Mexican, arab etc. Some of them come up wanting a pin that I do not have. I feel like that guy fighting the whale.
By the way, thanks

By the way, Its not about the phone, its my backup...its about the right way to do this, and its about me understanding it. I like LG and just want be comfortable doing these things with my LG Phone. I have flashed custom roms with my S3 back a few years ago, but this is a new batch of challenges. I really appreciate all the help!

OK, if I gt a stock phone...
If I buy another Used LG Stock ATT Optimus Pro, can I back up its ROM and restore it to my bricked optimus? How would I do that?
I could use TWRP for that?

It would have been quicker if I could have read Korean. The Phone has a baseband, and recognizes my Sim, but is still not on AT&T. What is causing this...anyone???

Tried rooting today -- soft brick

Edit: The Verizon repair assistant put my phone back to PHE build [100% battery].
Man I knew I shouldn't have tried to root after all this time. I'm not sure which firmware my phone was on [it was the 60% battery update], either PHE or PK1, as it displays in recovery right now. I tried to follow Lrileys modification of freeza's root guide, which neither of them specify a base firmware to go off of, lol.
Anyways, flashing the userdebug sprint firmware with ODIN 3.12.4 failed and my device softbricked. It boots into recovery and download mode.
I have tried factory reset, wiping cache partition, flashing an AP PH1 firmware, and repair through Verizon software/upgrade assistant.
The closest I've gotten to restoring it was with VUA, however when I go to the repair assistant page, it tells me to put phone in download mode [which I do] but the repair button stays greyed out.
Any help would be greatly appreciated.
Edit: The Verizon Upgrade Assistant wasn't starting, saying it was missing mfc90.dll. Well I downloaded the dll, dropped it in the folder, and was able to get UA to recognize phone. Repair assistant is downloading software right now, we'll see how it goes.
IF you would have read there is no root for the PHE.. you also could have checked this via phone settings before you rooted.
You can also use the verizon app to restore your firmware from even the most bricked of phones. Also in in this forum..(looks like you might have tried this?)
I wouldnt even bother at this point, go get your temp phone =]

Well the repair assistant seems to be working atm, so hopefully it goes through without any problems. Neither of these threads in the original post mentioned anything about incompatible firmware though [https://forum.xda-developers.com/verizon-note-7/how-to/root-vzw-note-7-t3448711 and https://forum.xda-developers.com/sprint-note-7/how-to/root-super-leaky-bros-sprint-galaxy-t3447202]. I suppose I should have known trying to use a method that dated.
You shouldn't be messing with this stuff if you don't even know how to see what version your on and read.
very helpful

Thank you for the gratuitous reply. Despite your sour attitude I was able to return to PHE through VUA. I was running PK1 firmware, however, again, neither root method specified/recommended/listed a base or stock firmware to flash from [or even posted what they were running]. This place used to be helpful.

Does reverting to 5.0 from 6.0 brick your phone? Rooting/Downgrading Help!

I have tried every method I can find to root my g3 6.0. Kingroot, PurpleDrake, etc. I've tried every method to revert back to 5.0 I can find, LGUP, LG Flashtool 2014 and 2015, none of them work.
I then decided to give up and pay a shop to do it for me. But when I asked about it, they said they couldn't do it. Reason being that 6.0 updated the boot loader, and if you tried to revert, it would brick the phone. If this true or did they just not know what they were doing?
If anyone can help me to root this phone or revert to 5.0 I'd really appreciate it! Nothing I find seems to work.
If you have D855 reverting with LGUP works.

Is there any truth to downgrading bricking my phone?
I can't really tell. I think no. BTW did you even tried to downgrade with LGUP or you write nonsense in OP?
No I did try the guide on https://forum.xda-developers.com/showthread.php?t=2785089
When trying KDZ method, it just stops after loading the LG update tool, tells me it encountered an error, or it couldnt connect to the server. I tried leaving it for 15 mins, then unplugging and replugging it back in, nothing happend.
When trying TOT method, I get a version mismatch. I know I have the right version of files but nothing.
Looks like there has been no luck rooting Canadian G3 so far: https://forum.xda-developers.com/lg-g3/help/root-d852-canada-marshmallow-6-0-t3356842

I had the same problem with the KDZ method. Did it ask you if you wanted to retry? When I chose to retry, it worked fine afterwards. *
*Caveat...someone told me that that unable to connect error is a false error and that it should just continue after clicking retry. I wound up having to unplug my phone, pull the battery, rebooted/reconnected into download mode, chose the retry button and it worked.
i have successfully downgraded from MM to LL following this post.
